I got the same results which leads me to suspect that the original
tip is faulty.
The tip may not be faulty.
Perhaps you should try it and then make a pronouncement!
You could do this in a directory with a few files:
$ mkdir /tmp/faultyfindq; cd /tmp/faultyfindq
$ touch a{1..4}
$ find . -type f | xargs nano
If you manage to do something sensible with the last command, then
please report it. (I have replaced vi with nano since Roshan seems to
dislike vi).
I suspect the problem is explained in this snippet from the man page
for xargs:
--arg-file=file
-a file
Read items from file instead of standard input. If you use
this option, stdin remains unchanged when commands are run.
Otherwise, stdin is redirected from /dev/null.
So the problem is that vi is run with stdin redirected from /dev/null
which will obviously not work.
